STARTER.

Application filed May 15, 1917.

To 0/6 whom it may oam/r11:

lie it known that l. tlononnns A. l. .\liilt)'l."l., a :tizen ot the United tltates, residing at 'l exarlmna, in the county of Bowie and t tate ol Texas, have inrenteiil new and. uselul lnlproremcnts in Starters, ot which the tollowiirg is a specification.

lily invention relates to starters tor intcrnal combustion motors and has for its primary object. to provide a starter which will not transmit the. occasional backward kick oi the motor and result in injury to the operator.

.t :t'urther ()lIlQClJ of mg. invention is to provide means :l'or locking the starter in an inoperatire position to prevent: unauthorized operation oi" the motor.

With these and other objects in view which will he hereinafter fully described and particularly pointed out in the claims, the invention consists in the. novel construetion and arrangement or. parts illustrated in the aecompanyirig drawings, forming a part oi. this specification, in which:

Figure 1 is a partial side elevation (it an internal con'ihustion motor to which a starter emhodving; my invention is attached.

Fin. 2 is a top plan view of the starter, the top of the casing having been removed to more clearly show the operating parts there-o t.

Fin. 3 is av similar view showing;- the clutch oi the starter in engagement; with a corresponding clutch on the crank sha tt of the motor preparatory to starting the motor.

li ke. characters oil. rehirence indicate like pa rts in the various views.

in the drawings .1 designates generally an internal comlinistiou motor Which is pro rided with a crank sha'tit said crank shaft. normally rotating in a clockwise direction as is the usual practice. The forward end of the crank shaft is provided with a laterally faced receding cam type clutch the clutching: faces of the clutch t ara inn in a counter-clockwise direction.

Mounted on the structure of the motor is a frame 5 comprising a rear plate 6 and :Iront plate 7, the edges of said front plate 7 lieino turned hack to form the top. hot- Spccificaticn of Letters Patent.

tom, and ends 01 the frame, the rear edges of said top, bottom and ends l'ieing turned outwardly to jlforni flanges 23, am said flanges are secured to the rear plate t) by means of l olts 9. 1i shaft it.) is amunted tor rotation and tor longitudinal movement in a boss ll, torineijl on the rear plate 7 and is disposed in axial alinenient with the crank shaft :2. The rear end ol? the st aft 10 is provided with a laterallv faced recedii'ig cam type clutch 11%, the clutching :taces 13 of which are taced in a clockwise direction, and are adapted to engage the clutching faces 4-, when the shaft 10 moved inwardly to rotate the crank slialft Z in a elocliiu'ise di- .rection. A n extension l-l; is formed upon the rear surface ot' the plate (3 and extends rearn'ardlr therefrom and has a hearing 15 engaging the shaft it) immediately in front of the clutch A coiled coi'upressiou spring 1t) encircles said shaft. 10 just in front of the bearing 15, and has its rear end abutting the same, and has its front end abutting a collar 1? mounted upon the shaft ll). tiaid spring 15 serves to m rn1all ""tain the shaft 10 in its outer position with the clutch l2 disengaged from the clutch 3. A shaft 18 is mounted for rotation and for longitudinal movement in a boss 1 oi. the front plate flaid shaft 18 is n'e'l erahly disposed in axial alineincnt with t he shaft 10, and has a gear 20 mounted the inner end thereof, said rear lying just in hackotthe :trontplate'l'and abutting the outer face of a gear 2i mounted upon the outer end ot' the shaltt 10. A cranking handle 22 is mounted. upon the outer end of the shaft 18. it shaft 23 mounted in a air of slots it formed in respective plates t3 and T, said slots being disposed radian respecting the shaft 10. A yoke 25 has respective arms thereon secured to the shaft 23 adjacent respective slots 2:1, and a rod 26 has its one end secured to the transverse portion of the yoke and extends through the hole :27 formed in the end incinher of the frame A gear '28 is rotatably mounted upon the shaft 23 between the arms of the yoke and is adapted, when the yoke is moved toward the shaft 10, to mesh with the gears 20 and 21. AL coiled con pression spring;- 29 encircles the rod 26 and aim ts the yoke and the end of the frame with its respective ends whereby said gear 28 is normally held in meshed engagement with the gears 20 and 21. The ends or the slots 24, which lie nearest the shafts 10 and 18 serve to prevent spring 29 from meshing the gears too tight. A separating shield 30 is mounted for pivotal movement upon the shaft 23 by means of arms 31 extending downwardly on either side of the gear 28 engaging said shaft with 1ournals between the respective arms of the yoke 25 and the gear 28. 1h lug is formed upon the separating shield 30, and a pair of stops 33 are formed on the rear plate 6 and are disposed in the path of movement of the lug 32 to limit the movement of the shield 30 in both directions. A pawl 33 is pivotally mounted upon the shield 30 and is adapted to engage the teeth of the gear 28, and is so disposed that whe the gear 28 rotates in a clockwise direction the gear will rotate the shield through the medium of the pawl. A. fiat spring 3% has its one end secured upon the shield 30 and engages the pawl with its other end and hold the pawl in engagement with the teeth of the gear 2 A tongue 35 is formed upon the shield 30 and is adapted to pass between the gear 28 and the gears 20 and 21 to support the same against the influence of the spring 29 when. the gear 28 is rotated in a clockwise direction and the shield .is moved thereby through tl e medimn of the pawl 33, as hereinbefore described. A coil spring 35 has its one end connected to the shield 30 and its other end connected to the rear plate 6, and serves to normally position the tongue of the shield out of engagement with the gear, said lug 32 to respective stop 33 serving to prevent said spring from moving the shield too far.

It will be noted from the above description, that the shield 30 is held in an inoperative position when the gears :20 and 21 are rotated. in a clockwise direction. and the gear :28 rotates in. a counter-clockwise direction. However, when the gears 20 and 21 rotate in a conliter-clockwise direction and the gear 28 rotates in a clockwise direction. the pawl 33 engages the teeth of the gear 28 and the shield is moved therewith in a clockwise direction whereby the tongue 35 is driven in between the gear 28 and the gears 20 and 2-, and the gear 26 is moved out of engagement with the ears 20 and 21 against the influence of the spring 29. As soon as the gears are separated the gear stops rotating the gears 20 and 21 slip over the surface of the tongue 35, the friction of said gears 20 and 21 serving to hold the lug 32 against the respective stop 33, against the influence of spring When the mechanism is in this position the gears 20 and 21 are out of driving conned tion with each other, see Fig. 41:. Thus it will be seen that while the gears 20 and 21 are rotated in a clockwise direction a dr'ving connection may be maintained therebetween, whereas, when the gears 20 and 521 are ro- Leas es tated in a counter-clockwise direction the shield 30 breaks the driving connection between the gears 20 and 21, and prevents the shaft 10 from rotating the shaft 18 in a counter-clockwise direction, as would be the case if the motor I. kicked back while it was being cranked.

The rod 26 extends some distance beyond the hole 27 and has a pivot stud 36 mounted near the outer end thereof. A cam lever 3'? is pivoted upon said stud at a point intermediate its ends and has a'cam surface 38 formed at one end thereof, which engages the outer surface of the frame adja cent the hole 7 when the cam lever is actuated to withdraw the rod out of the hole. A transverse hole 29 is formed in the rod 27 at the outer end thereof, and a hole d0 is formed in the cam lever 37 which. is adapted to register with said hole 39 when the cam lever is positioned to hold said rod in its retracted position. When in this position the hasp 4-1 of an ordinary padlock l2 may be inserted in said holes to lock the rod in its ret acted position. W hen the rod 27 is in a retracted position the gear 28 is withdrawn from engagement with the gears 20 and :21, the gears 20 and 21 are out of driving connection with each other. Thusit will be seen, that by locking the rod 27 951 in its retracted position the starter may be rendered inoperative to prevent unauthori'laed operation of the motor.
